To oli whom 'iL may concern:

Be it known that I, FREDRLCK HARTJE, a citizen of `thegUnited States, residing at St'. lliomas, in the county oi .Pembina and State of North Dakota, have invented certain new and useful Improvements in Alu* tomobile Sleighs, ofv which the cation. v

My invention relates to automobile sleighs, and has ier its object to provide certain improvements in the construction of the saine as will be hereinafter more definitely pointed out and claimed;reference being Iliad to the accompanying drawings, in which I' Figure 1 is a side elevation, partly broken away,4 oi my improved construction. Fig. 2 is a bottom plan. view of the same with the runners removed. Fig. 3 is an enlarged detail side elevation of one oi` the. drive wheels. Fig. 4 is anenlarged vertical'transverse sec- 'tional 'view oi the saine. Fig. .5 is anenlarged detail" sectional view taken on the line 5-5, Fig. 1.

' Similarl numerals of reference denote 'corresponding parts in the several views. I

in the said drawings the reference Inumeral 1 denotes the body ofthe automobile, which may he of anysuitable lconstruction, agasolene, steam or othersuitable motor'being located in the compartment 2 to the rear oi the rear seat. The vparticular form oi, motor and the means for controlling the same from the drivers seat forming no part oi the present invention, the same are not shown in the drawing. p

Ocenpyin'g the-usual position at the front oi the vehicle isa steeringwheel .3, carrying 'at its lower end a bevel gear Ai, in mesh with a similar gear 5, mounted on the central post 6 of the iront runners 7 ,i a suitable iiith wheel -8 beinginterposed between said runner frame and the vehicle body, the whole affording means ier turning said runners and steering the vehicle.

ilivoted at 9 to one loi vthe side bars 1() of the vehicle body 1 is a lever 11 extended within reach ofthe drivers scat, andprovided with the usual locking rod'12" side bars 10. Said bell-crank lever carries at theend oi its other arm 16/ one end oi the drive wheel shaft 17,

the other end of .saidI shaft being supported b y an armi 18 similarly pivoted to the other end of said transverse bar lo; the upper part of the bellcrank lever being provided with a lip 17 which engages the Ylower portion 163/, to elevate the same.

lincircling the transverse bar 16' between the vehicle side bars 10 is a sleeve 19, having keyed thereon a central sprocket Wheel and similar sprocket wheels 21 disposed on each'side of said central sprocket wheel,

a drive chain 22 connecting the motor a-nd said sprocket wheel 20iforming means for driving said sleeve 19 andl sprocket .wheels 21. Keyed to the drive Wheel shaft.v

l 17 are apluralit'y of 'drive Wheels 2.3, hereinafter described, the rotation'oi sleeve 19 beingA impartedftd said shaft 17, throughspr'ocket chains 24 connecting sprocket wheels l21 with .'sirnilar sprocket wheels 25 l key-@d aan Shaft A17. f l l The rear ends 26 of th'e side bars 10 are extended upwardly at an angle andare provided on their under sides with sockets 27, in which ares'eatedthe upperl ends of coiled springs 28, seated at their lower ends in similar sockets 29 formed on the bell crank levers l5 and bar 18, said springs serving to resist and cushion inequalities in the surface traversed.

'Extending irom'the. motor compartment 2 .to the ends of the extensions 26 is a shield 3Q, having pivotd thereto at its outer end an'extelis'ion shield 31 that 'is otherwise supported to rise and fall with the drive `wheelsl23 by means of bars 32 pivoted thereto and to 4 the drive Wheel shaft 17, this construction effectually i covering thel drive 'wheels and yet following the very' tical movement thereof.

The drive wheels 23 consist each oi a1 hub -away annularly at one side andl screw-'threaded to re.-

ceive a similarly screw-threaded sleeve 3 4, the ends of the 'spokes 35 bein'gl'securely clamped betweensaid hub and sleeve, asbest seenin Fig. 4, suitable retainpins 36 beingV employed if desired `to more firmly retain said ,spokes in position', Said spokes'extend outwardly 4through a metallic rim 37, being provided' with shoulders 38,150 positionsaid rim, and terminate in spiked ends 39 adapted to engage the surface Itraveled over; Intermediate the spokes I provide similar spikes 40 ixed in the rim 37 to vprovide a large number of engaging points without increasing the number of spokes. It will be' observed that by dividing the bell crank lever, the shaft 17 carrying the drive wheels 23, 'can move vertically independent of the elevating de?.

that by means of lever'll, connecting rod 14 and bell- .l

thereof are pivoted concentrica'.lly withI the sleeve 19 through which said drivevwheels are driven, whereby I the variation in the vertical position of the drivewheel shaft 17 will not affect the tension of sprocket chainsgZ/l:

Having thus described my inventiornlwhat claim as new and desire to securefby Letters Patent, isz- A 1. In an automobile4 sleigh, a series of drive wheels adapted towenga'ge the sui-face traversed, armssupp'rting.

theshart of said drive wheels, -a transverse-.bar to which -the inner ends of said arms are connected, means-for -i-oekiny.: said Y:ii-ms to raise or lower said shaft :ind drive wheels. ar Sleeve encircling said transverse: hair, a motor. und connections between said motor and sleeve und smid sleeve und drive wheel shaft for rotating the latter.

22 In in automobile sleigh, a series of drive wheels adapted to eng-age the' surface traversed, means for rotat-v ing; said wheels` means for .shifting said wheels vertically. n shield pivoted to the automobile body and covering 'sziid drive wheels, and eonneetions between the drive wheel shui und said shield whereby vertical movvmvm inlmrlm' ro said .drive wheels will he siuiil-.irly iinlmrlod lo .mid shield.l l

.In testimony whereof I have hereunto ser my hund ii: the presence of two 'subscribing`- wirmfsses.
